Acting impassively means showing no emotion or feeling. It's like having a blank expression, no matter what's happening around you. You might hear shocking news or witness something amazing, but your face remains the same. Think of a stone statueβunmoved and unexpressive. Impassivity can be a defense mechanism, or it can simply be a personality trait. It doesn't necessarily mean you don't care, just that you don't show it outwardly.
